Both heavy Calcium Carbonate (referred to as heavy calcium) and light Calcium Carbonate (referred to as light calcium) are the most widely used powder fillers in the plastics industry.

Both heavy Calcium Carbonate (referred to as heavy calcium) and light Calcium Carbonate (referred to as light calcium) are the most widely used powder fillers in the plastics industry. This paper introduces the difference between heavy Calcium Carbonate and light Calcium Carbonate from 17 different perspectives, such as production method, bulk density, oil absorption value, whiteness, moisture content, and particle properties.

Calcium Carbonate can not only reduce the raw material cost of plastic products, but also improve some properties of plastic materials. Research results show that different types of Calcium Carbonate can significantly improve the performance of the matrix plastic when used properly, but the specific distinction between lightweight Calcium Carbonate and heavy Calcium Carbonate has always puzzled most users.

Calcium Carbonate

Heavy Calcium Carbonate is mainly a powder material obtained by mechanical grinding with natural minerals such as calcite, marble, limestone, chalk, and white marble as raw materials;

Light Calcium Carbonate is mainly a powder material obtained from limestone as raw material through calcination, digestion, carbonization, dehydration, drying, classification and other processes.
